MSA FlameGard 5 UV/IR & UV/IR-H2 Flame Detectors


Ultraviolet and infrared flame detection provides high immunity to false alarms

The FlameGard 5 UV/IR Flame Detector is designed to detect fires and provide alarm outputs directly from the detector while maintaining false alarm immunity. The FlameGard 5 UV/IR-H2 detects hydrogen fires.

The two models detect fires by monitoring in both the ultraviolet and infrared (UV & IR) spectral ranges, making it highly immune to false alarms caused by lightning, arc welding, hot objects and other sources of radiation.

The electronics of the FlameGard 5 UV/IR and UV/IR-H2 detectors are housed in an aluminium explosion-proof enclosure (Stainless Steel optional).

The detector is available with the following output configurations:

  4–20 mA stepped output
  Warning, alarm and fault relays
  Modbus RTU (up to 128 units, or 247 units using repeaters to be linked up to a host computer)
  HART communication

The Modbus and HART outputs provide alarm status, fault and other information for operating, troubleshooting or programming the unit. HART enables this feature without the need for rewiring.

The continuous optical path monitoring (COPM) self test feature checks both the optical path integrity (window cleanliness) and the de tector’s electronic circuitry once every minute.

Features and Benefits

  Wide field of view enables greater fire detection coverage
  Event logging stores fault and alarm history
  4 –20 mA stepped output is the industry standard for remote alarm and fault indication
  Modbus and HART user interface provides complete status and control capability in the control room
  Wide operating temperature range permits operation at higher ambient temperature
  Continuous Optical Path Monitoring (COPM) checks the optical path integrity and the detector’s electronic circuitry once every minute
  Three SPDT high-current programmable relay outputs provide immediate and timedelayed relay outputs for alarm, warning and fault conditions
